X(30), X(74), X(399), X(1138), X(1511) reflection of X(1138) in X(1511) 

K614 ia central focal cubic with center and focus the midpoint X(1511) of X(3)X(110) and X(74)X(399). K614 and its isogonal transform generate a pencil of cubics, stable under isogonal conjugation, that contains the Neuberg cubic K001 and two decomposed cubics namely :
This pencil also contains one isogonal circular nK with focus X(74) and, more generally, the singular focus of any cubic of the pencil is a point on the line X(3), X(110) = focus of K001.
